The Seattle Mariners and GM Jerry Dipoto have been busy this offseason, pulling the trigger on 11 trades and signing numerous players. Here is one sentence on every big-leaguer the club has acquired since the end of the 2016 regular season.

Carlos Ruiz, C

Terrific veteran No. 2 catcher with more to offer defensively than Chris Ianetta.

Danny Valencia, IF/OF

An all-around upgrade to Dae-ho Lee and a serviceable option at 3B to get Kyle Seager a little more rest.

Taylor Motter, UT

Reserve with a chance to be useful bench player despite fitting best at 3B, 1B and the corner outfield spots — not shortstop or second base.

Mitch Haniger, OF

Solid athlete, good arm, perhaps enough plate skills to be ready to help right away in 2017.

Yovani Gallardo, RHP

Solid bounce-back candidate who posted 4.00 FIP in Arlington in 2015 and has seven straight season surpassing 180 innings.

Zac Curtis, LHP

Depth lefty for bullpen with low-90s FB and a slider he loves to throw.

Casey Fien, RHP

Depth righty for bullpen with MLB experience and no strikeout pitch.

Chris Heston, RHP

Depth righty for rotation; below average velo (87-89 mph) but has flashed back-end starter ability.

James Pazos, LHP

Sturdy southpaw up to 97 with sinking fastball and solid-average slider and a chance to make club out of spring training.

Marc Rzepczynski, LHP

Proven left-hander whose velo ticked up in ’16 (91-93) basically fills Vidal Nuno’s role from past two years

Shae Simmons, RHP

Once-promising closer prospect regained most of previous velo (averaged 95 mph in 2016) but slider and command still stranded somewhere.

Drew Smyly, LHP

Perfect fit for Mariners rotation and a chance to take advantage of ballpark-defense combo.

Rob Whalen, RHP

Despite lack of plus velo (88-91) misses just enough bats to start thanks to sinker-slider combo.

Jean Segura, SS

The Mariners have found a leadoff hitter, plain and simple.

Jarrod Dyson, OF

Quality role player is a legitimate CF glove and a huge plus on the bases.

Kyle Waldrop, OF

Lefty stick with above-average raw power who figures to start season in Tacoma and serve as emergency depth.
