EDGE Analysis

The 22-year-old shortstop had been struggling to date, having come into Monday's action with a .214 average. His four-hit effort, which was just a homer short of the cycle, boosted that figure to .253. It was Robertson's third multi-hit game of the season, and he's now slashing .253/.360/.360 over 75 at-bats. Major league shortstops Brad Miller and Tim Beckham are both notably hitting under the Mendoza line to date this season, something to monitor if their numbers and Robertson's continue to head in opposite direction.

The Rays confirmed Monday that Robertson (hand) has a fractured hamate bone in his right hand, Marc Topkin of the Tampa Bay Times reports. The top shortstop prospect will undergo surgery Tuesday, and the expectation is that Robertson will be able to return at some point later this season. Robertson is hitting .272/.347/.436 in 49 games at Double-A Montgomery this season after tearing it up at High-A Stockton in 2014 to the tune of a .310/.402/.471 slash line.

Robertson is being evaluated for a possible broken hamate bone in his left hand, the Tampa Tribune reports. If his injury is confirmed to be a broken hamate bone, the 21-year-old Robertson will be in danger of missing the rest of 2015. One of the top prospects in Tampa Bay's organization, he owns a .272/.347/.436 slash line through 49 games for Double-A Montgomery this season, after posting a .310/.402/.471 slash line over 132 games for High-A Stockton last year. While it's unclear if he has the defensive chops to stick at shortstop long term, Robertson has a very advanced bat for his age.

Robertson went 3-for-4 with a homer, two doubles, and three RBI in game for Double-A Montgomery on Saturday. The 21-year-old's long-term future at shortstop remains muddled due to defensive concerns, but he's experienced no such trouble adjusting to pitching at the Double-A level. Saturday's performance raised his season line up to .283/.386/.481, numbers comparable to those he posted in the California League in 2014.
