• Cain makes second start, SF @ OAK, 4:05 p.m. ET
Giants right-hander Matt Cain showed little rust in his spring debut, working two perfect innings against the Dodgers. That was a great sign for Cain, who underwent season-ending surgery on his right elbow last August. He and the Giants will be looking for another solid outing on Saturday.
"That went really [well]," Cain said. "I've been trying to think a lot lately about trying to get in the right rhythm, trying to get everything in the same groove, and then it all kind of worked out."
• Young arms on display, MIN @ STL, 1:05 p.m. ET
Cardinals right-hander Michael Wacha dazzled in his first spring start, striking out four Red Sox in two perfect innings. He'll look to match that in his second start.
"The ball looks like it's jumping," Cardinals manager Mike Matheny said. "I think that's a key for him, because there are not many guys in the league who have that look. And that's what makes his changeup so good."
Right-hander Alex Meyer, ranked as the No. 30 overall prospect by MLB.com, is scheduled to see action for the Twins.
• Walker looks to keep scoreless streak alive, SEA @ ARI, 4:10 p.m. ET
Mariners right-hander Taijuan Walker has been impressive this spring, allowing only two hits in five scoreless innings while striking out six. He'll make his third start Saturday against the D-backs.
"Everything felt good," said Walker, who is competing with Roenis Elias for the fifth starting spot. "I feel confident, healthy and strong."
• Rotation battles continue
Earning Major League rotation spots is tough, and there's a number of them available throughout the Cactus and Grapefruit Leagues. Among those pitching Saturday who are battling for spots: Rays right-hander Nathan Karns (TB @ BAL, 1:05 p.m. ET), Blue Jays left-hander Daniel Norris (NYY @ TOR, 1:07 p.m. ET), Braves lefty Wandy Rodriguez (HOU @ ATL, 6:05 p.m. ET) and Indians righty Josh Tomlin (CLE @ LAD, 4:05 p.m. ET).
• Angels' Baldoquin arrives in camp
Twenty-one-year-old Cuban infielder Roberto Baldoquin, who received an $8 million signing bonus from the Angels, has arrived in camp and will be introduced Saturday. The 5-foot-11, 176-pound Baldoquin likely will start the season at either Class A Advanced Inland Empire or Double-A Arkansas, exclusively playing shortstop, but the Halos expect him to advance quickly.
"We're going to let him tell us when it's time to move," Angels general manager Jerry Dipoto said during the Winter Meetings, "but he's a pretty advanced player. He's a confident kid who understands what he is, what he can do."
