• After working at second base in Tuesday's infield drills, utility man Willie Bloomquist on Wednesday moved to third base and took grounders alongside Seager. Bloomquist can play second, short and third as well as the outfield, which is why McClendon welcomes his veteran presence.
"That was my first signing when I got here," McClendon said. "That was the first guy I thought we needed to go after, because this guy is so important to a ballclub. To have a veteran guy that can move around and do a lot of different things really gives you options on a daily basis. Particularly with the traveling we do, I thought it was really important we target the right guy, and I think we got the right guy."
• After working on bunting drills Tuesday, the Mariners held a session on pickoff drills Wednesday. One season each day of camp will focus on a different fundamental.
• Coaches threw batting practice again Wednesday, but hitters will switch over to live batting practice against their pitchers starting Thursday. Hitters typically do not swing at pitches much the first day or two of live BP in order to get their timing down and work on tracking the ball.
About half the pitchers in camp threw bullpen sessions Tuesday, including James Paxton, Randy Wolf, Brandon Maurer, Fernando Rodney, Mark Rogers, Danny Farquhar, Charlie Furbush, Bobby LaFromboise, Zach Miner, Hector Noesi, Yoervis Medina and Logan Bawcom.
Also throwing were Minor League invitees Jonathan Arias, Stephen Kohlscheen, Carson Smith, Roenis Elias and Ramon Ramirez.
The other half of the pitching staff will take the mound for live BP sessions -- including Erasmo Ramirez, Tom Wilhelmsen, Lucas Luetge, Blake Beavan and veteran non-roster invitee Joe Beimel -- though Felix Hernandez and Taijuan Walker are on a slower schedule and will instead throw their second bullpens of camp on Thursday.
