The Minnesota Twins promoted minor-league infielder Luke Keaschall, a 22-year-old Aptos High alum, to provide a spark to their injury-plagued lineup last week. Now, they have yet another injury to deal with.

Keaschall, off to a sensational start to begin his MLB career, suffered a non-displaced fracture in his right forearm after being struck by a pitch during the Twins’ 11-4 win over the visiting Los Angeles Angels on Friday night.

The 57th ranked prospect in MLB and No. 3 prospect in the Twins’ system is expected to missed an extended period of time, manager Rocco Baldelli said during his post-game conference with media.

“He’s going to miss some time, obviously,” Baldelli said. “It’s a a non-displaced fracture, which is a good thing, but we’re going to have to take out time …. I don’t have a real timeline or anything. At this point we’re going to wait and see that the further opinions tell us. Obviously, that’s tough news. He’s settling in well here and doing a real nice job for us. He’ll be back. He’ll get it right and he’ll be back.”

The designated hitter, batting third in the lineup, stayed in the game after being struck by Kyle Hendricks’ pitch in the first inning. He was replaced by Mickey Gasper prior to his next plate appearance.

“He (Keaschall) went in and tried to do some stuff in the cage before in between innings and we learned pretty quickly that he wasn’t going to be able to,” Baldelli said.

Since his promotion, Keaschall has been an on-base machine for the Twins. He started seven straight games and was batting .368 (7 for 19) with three doubles, five walks, five stolen bases, two RBI, and four runs scored.

“He’s been extremely impressive” Baldelli said. “And his attitude’s great, and he really likes to work. When you have young players with really good ability that really like to work, really like to work, it kinda brews up and has the making of a guy who can play here for a long time.”

Keaschall reached base 13 times in his first six games, one shy of matching the Twins’ all-time set by Baseball Hall of Famer Kirby Puckett.

With two steals in Wednesday’s win over the Chicago White Sox, Keaschall tied the all-time MLB record for most stolen bases (five) by a player after their first five career games, joining Luis Castillo (1996), Ced Landrum (1991), Donell Nixon (1987) and Vince Coleman (1985).
