As I see it, the 48-year-old executive envisions a foundation of athletic and accomplished players, who are adept at reaching base and wreaking havoc through productive aggressiveness on the bases.
Equally important are outfield defenders who can run down balls in Safeco’s spacious outfield. In Dipoto’s world, a run save is as valuable as a run scored.
To be honest, I thought this season’s Opening Day roster was a massive upgrade over the 2015 version of the Mariners. I’ve been saying as much in previous Prospect Insider pieces and on Twitter. But, the more I think about it, the club has fallen short in a couple of those key areas targeted by Dipoto during the offseason.
This finally became glaringly clear to me in late June when watching the Pittsburgh Pirates take on the Mariners at Safeco. I was thoroughly impressed with the athleticism, speed, and on-base ability of the Pirates. So was Mike Salk of 710 ESPN Seattle, who took to Twitter to deliver his assessment of the visiting team’s roster.
The Pirates are built for Safeco.

The simple and straightforward comment from the co-host of the Brock and Salk Show hit the nail right on the head — Pittsburgh was better built for Safeco than the home team. This gave me the idea to dig into the Mariners’ home field suitability and look around the league for the teams best built for Safeco.
To get a better feel of where the Mariners stand this season, I decided to see where the team’s on-base ability, outfield defense, and base running ranked against the other 29 major league clubs. I also compared those rankings to last year’s to gauge Seattle’s improvement. Overall, the numbers weren’t encouraging.
|Mariners MLB Rankings|
|Season||On-Base Ability||Outfield Defense (DRS)
As you can see, the Mariners have significantly improved in just one area — reaching base. That’s clearly evident by their top-10 on-base percentage (OBP). Unfortunately, for the ball club and its fans, that’s the only area worth bragging about.
Based on defensive runs saved (DRS), Seattle’s outfield defense isn’t good enough. The addition of center fielder Leonys Martin was a step in the right direction. However, last season’s core of corner outfielders — Seth Smith, Nelson Cruz, and Franklin Gutierrez — remain on the roster.
The trio has combined to play 65-percent of all left and right field innings this season. Based on the defensive metrics, they’re all below-average fielders — as they were last season. This does not bode well for an organization trying to improve their outfield defense.
Nori Aoki was brought in to help the club’s outfield defense, team speed and on-base ability. To date, he’s under-performed in all three areas and finds himself playing for Class-AAA Tacoma as a result. Aoki will likely return to the big league club in the near future. Perhaps, he’ll get his season back on track and help the Mariners make a pennant push.
On the base paths, there’s only one way for me to put it — the baby is ugly. Seattle base runners have cost the team runs and continue to rank at the bottom of the league in both sabermetric and standard base running statistics.
BsR (Base Running) is a FanGraphs statistic that takes into account all aspects of base path action — stolen base success, taking extra bases, being thrown out while on base, etc. If you’ve been watching the Mariners over the last few seasons, their low standing doesn’t surprise you.
The same goes for stolen base percentage (SB%), which is the old-fashioned measurement of how successful a base runner has been at stealing bases. Not only is Seattle still at the bottom of the league, their 53-percent success rate is eight points lower than last season.
Now that I’ve established that the Mariners have a lot of work to do, let’s turn our attention to clubs that I believe are a far better fit for Safeco Field than the home team; based on on-base ability, outfield range, and team speed. Let’s start with the club mentioned by Mr. Salk.
As good as the Pirates look, their roster isn’t the best fit for Safeco among the clubs I plan to discuss. But, their stable of players exemplifies the type of players that fit the mold of what Dipoto has been publicly advocating, especially in the outfield.
The starting trio of Andrew McCutchen, Starling Marte, and Gregory Polanco form one of the most athletic starting outfields in the majors. Marte leads all major league left fielders in DRS and Polanco ranks tenth among right fielders. Defensive metrics don’t love McCutchen, which confounded me, until I spoke to Prospect Insider founder Jason A. Churchill.
Jason pointed out that Marte/Polanco may be the best corner outfield combo in the majors and that they reach balls in the gaps their peers can’t. As a result, their defensive excellence could be creating the appearance that McCutchen has limited range. Even if McCutchen’s poor DRS accurately portrayed his defensive prowess, the Pirates total outfield is slightly above average, which is all that really matters for any club.
Pittsburgh’s offense is a deep unit that ended the first half of the season with the third best OBP in the big leagues. The club brags nine players — including the rehabbing Francisco Cervelli — with 150 or more plate appearance and an OBP above the league-average (.323). By comparison, the productive Mariners offense has five.
Team speed has been an important element in the Pittsburgh attack. Their base runners entered the all-star break tied with the Houston Astros for third most stolen bases (68) in the big leagues and the fifth best success rate — 76-percent. Leading the way for the Bucs is Marte, who entered the break with 30 swiped bags — second most in the majors.
The Pirates are certainly a better fit for Safeco than the current edition of the Mariners. But, there are two other rosters I like more. The next team has been better known for relying on offensive firepower — not speed, defense, and athleticism.
Boston Red Sox
Boston’s offense reached the all-star break leading the majors in OBP and slugging percentage. In years past, you might have assumed the long ball was the driving force behind their prolific slugging — not in 2016. This version of the Red Sox is only league-average at hitting home runs, but leads the league in doubles and top-10 in triples.
All things considered, the team’s outfield defense has fared well even though left field has been problematic due to injuries to Chris Young, Blake Swihart, and Brock Holt at one time or another. Thanks to the dynamic duo of center fielder Jackie Bradley Jr. and right fielder Mookie Betts and Holt, the Red Sox outfield ranks number-five in the majors in DRS.
The club’s success on the base paths — third in the majors in BsR — is another new wrinkle in Beantown. Leading the way are Betts, Bradley, and shortstop Xander Bogaerts. Like the Pirates, the Red Sox are top-10 for stolen bases. More importantly, they have the highest success rate (86-percent) in the majors. That’s seven-percent better than the second best Cleveland Indians.
The Red Sox may play in the oldest ballpark in baseball, but they have a foundation of young, athletic ballplayers fueling their success in the outfield and throughout their lineup.
This season, the Red Sox have used 15 position players 28-years-old or younger. That’s tied for most in the majors. Among those players are Travis Shaw, Christian Vazquez, Bogaerts, Bradley, Betts, Swihart, and Holt. Yes, having young players doesn’t necessarily guarantee success. They have to be good AND young. That’s the case in Boston.
My favorite roster also plays in a ballpark opened before the start of World War I and employs Boston’s former general manager as their president of baseball operations.
Yes, picking the team with the second best record in the majors isn’t exactly a tough choice. But, I didn’t pick the team with the best record — the San Francisco Giants — and the other teams I’ve discussed started the second half in third place. While the Cubs could win in any park, including Yellowstone, they’d be a great fit for Safeco thanks to their superb on-base skills, outfield defense, and overall athleticism.
Chicago’s long lineup is second best in the majors at reaching base. How long is that lineup? All but one of the 12 position players on the current 25-man roster are above league average in OBP. There’s no breathing room for opposing pitchers when it comes to facing the Cubs’ lineup.
Defensively, the team’s outfield ranks third in the big leagues. The best of the bunch — right fielder Jason Heyward — continues to be an elite-level defender with the second best DRS. The 26-year-old has also logged over 120 innings of center field duty this season.
Regular center fielder Dexter Fowler — currently on the disabled list — isn’t on par with his partner in right field. But, his contributions along with Heyward and Albert Almora, have the Cubs center field defense ranked tenth in the big leagues. Thanks to Kris Bryant, Chris Coghlan, and Almora, Chicago’s left field contingent is also top-10.
Although the North Siders are below league-average in stolen base proficiency, they rank number-five in BsR because they’re adept at taking the extra base, which proves there’s more to base running than just stealing bases.
As with the Red Sox, Chicago boasts a bevvy of young stars. Six key contributors are 26-years-old or younger — Anthony Rizzo (26), Addison Russell (22), Bryant (24) , Heyward (26), Javier Baez (23), and Jorge Soler (24) – currently recovering from a hamstring injury. That’s not counting Kyle Schwarber (23), who’s lost for the year due to knee surgery.
The Cubs style of play works in any park, but their position players would be the best fit for Seattle’s home field. They’re athletic, get on base at a high rate, and play superb defense. That brings us back to the Emerald City’s major league baseball club.
Considering the roster that Dipoto started with last September, he’s done well at improving the club’s center field defense and their ability to reach base in less than a year. But, much more needs to be done to reach his stated goal of using the Safeco Field dimensions as an advantage. Getting younger would be a good first step.
Youthful rosters don’t necessarily guarantee success on the field. Look no further than the Minnesota Twins, who are great example of a young club with a terrible win-loss record. Also, not every young player is a great athlete — refer to Jesus Montero’s stay in Seattle.
Still, acquiring talented, young, and athletic players is the best way to build a sustainable home field advantage in Seattle. Having such players is the primary reason that the Red Sox and Cubs are better fits for Safeco — they each boast a half dozen or more quality players under age-27.
Conversely, the Mariners are tied with the New York Yankees for the oldest group of position players and have used just four under the age of 27 this season — Ketel Marte, Luis Sardinas, Chris Taylor, and Mike Zunino. Marte is the lone significant contributor, while Sardinas and Zunino have spent most of the season in Tacoma and Taylor is no longer with the organization.
Whether roster changes begin within the next two weeks or after the season, they’ll need to happen in order to turn Dipoto’s vision into reality for future seasons. That means more players born during the first term of the Clinton administration and fewer defensively challenged players like Gutierrez, Smith, and Cruz patrolling the outfield.
Can the Mariners accomplish such a turnover prior to next Opening Day? It seems unlikely considering the current state of their roster and minor league system. Until they do though, other clubs will continue to be a better fit for Safeco Field.
