Rays infielder Daniel Robertson, who went on the disabled list on Saturday with a sprained left thumb, will require surgery and is likely to miss the rest of the season, Bill Chastain of MLB.com reports.
Like the Rays themselves, owners of a respectable 56-55 record, Robertson has been a pleasant surprise in 2018. After struggling through a 254-plate appearance debut in 2017, when he hit .206/.308/.326, the 24-year-old Robertson has slashed .262/.382/.415 in 340 PAs this season.
Robertson hasn’t offered a ton of power (nine home runs, .152 ISO), though he’s tied for 21st in on-base percentage among hitters with at least 300 PAs and has registered appealing walk and strikeout rates (12.0 and 22.6 percent, respectively). Thanks largely to his on-base ability, which has been buoyed by 13 hit by pitches, Robertson has been 28 percent better than the league-average offensive player in 2018, according to FanGraphs’ wRC+ metric.
If Robertson’s season is indeed over, it’ll end with 2.6 fWAR and 2.8 rWAR, which would’ve made for impressive production even over a full campaign. But injuries have helped hold back Robertson, who previously missed time in June on account of a strained left hamstring and has played in just 87 games. Robertson showed off plenty of defensive versatility in that span, amassing anywhere from 19 to 39 appearances at third base, second base (his primary position) and shortstop.
