Description: Braves shortstop Andrelton Simmons is dealing with an oblique strain that will keep him out of the lineup for about a week.
Insight: He's a great glove man, but his fantasy value is limited by a mediocre bat. He hit .244 last season with seven homers, 46 RBI, 44 runs and four steals. He did hit 17 HR in 2013, so there may still be hope as he's only 25-years-old.
Description: Rockies shortstop Troy Tulowitzki (hip) did some base-running work on Monday, according to Nick Groke of The Denver Post.
Insight: It's another step in his progress toward Opening Day. Tulowitzki played just 91 games last year. The fantasy stud batted .340 with 21 homers, 52 RBI, 71 runs and a 1.035 OPS. He just has to get and stay healthy to be the anchor of your fantasy lineup.
Description: Seattle shortstop Chris Taylor will have to beat out Brad Miller in spring training if he wants to be the starter.
Insight: Neither figures to be anywhere near the top of the order. Miller batted .221 with 10 HR, 36 RBI and a .653 OPS in 367 at-bats last season, Taylor hit .287 with no homers, nine RBI and a .692 OPS in 136 at-bats. Taylor is thought to be the better fielder.
Description: Mariners shortstops Brad Miller and Chris Taylor will compete for the starting job, according to manager Lloyd McClendon.
Insight: Neither figures to be anywhere near the top of the order. Miller batted .221 with 10 HR, 36 RBI and a .653 OPS in 367 at-bats, Taylor hit .287 with no homers, nine RBI and a .692 OPS in 136 at-bats. Taylor is thought to be the better fielder.
Description: Shortstop Everth Cabrera is expected to sign a one-year deal with Baltimore on Tuesday.
Insight: Cabrera would vie for the second base job with Jonathan Schoop. If Cabrera gets significant time, he could be one of the best base-stealing second basemen for fantasy owners in 2015, but he's too one-dimensional for most fantasy lineups.
