Chicago is the latest team to join the trend of multiple hitting coaches, as the Cubs have hired Rob Deer to assist primary hitting coach James Rowson. Deer has been a hitting instructor in the Padres’ farm system and was teammates with Cubs manager Dale Sveum on the Brewers.
News of hitting and pitching coaches being hired is inevitably met with jokes about how that person wasn’t very good as a player and Deer is an easy target for that type of thinking (if you don’t believe me, just search his name on Twitter). He hit .220 during an 11-year career, led the league in strikeouts four times, and was the poster boy for all-or-nothing hitters in the 1980s.
Of course, those jokes conveniently ignore the fact that a) very few Hall of Fame-caliber players go into coaching when they retire, and b) most of the best, longest-tenured coaches across baseball had underwhelming playing careers.
In other words, the fact that Rob Deer hit .220 and struck out a ton means next to nothing about his coaching ability. If anything, Deer’s playing career was longer and better than the majority of hitting and pitching coaches. He smacked 230 homers and posted a .766 OPS that was solidly above average.
MLB.com’s Jenifer Langosch reports that Cardinals’ shortstop Aledmys Diaz has been sporting a new look around Busch Stadium with a pair of “strobe glasses,” technology-enhanced specs designed to help athletes focus on the ball. Like a strobe light, the lenses of these glasses affect a player’s vision by rapidly changing opacity, giving its wearers the illusion that the objects they see are moving more slowly than normal. Once a player adjusts to the new speed of play, they gain a greater sense of control and are able to time their actions with more precision.
Diaz isn’t the first MLB player to utilize the technology, just the first Cardinals’ player to do so. It’s been tested by Bryce Harper, Corey Brown, Tommy Joseph, Austin Hedges and Joe Mauer, among others around the league, and has been used for everything from refining a catcher’s reflexes behind the plate to tweaking a hitter’s ability to track a pitch. Per Langosch, Diaz has been using the glasses to hone in on the ball during pregame drills, increasing both his confidence and response time on the field and improving his defense at short.
The shortstop has been the focus of some concern this season after seeing a sizable dip in his production at the plate, and his five fielding errors, 0.6 UZR and 0.6 fWAR haven’t helped matters, either. He sustained a minor thumb injury during an at-bat on Friday night, and was left off of the Cardinals’ starting lineup on Saturday, though manager Mike Matheny didn’t rule out his ability to pinch-hit during the series. While the strobe glasses are a good start, Diaz will need more than a pair of specs to match the spotlight-worthy performance he turned out during his rookie season in 2016.
Red Sox’ left-hander Eduardo Rodriguez may finally get a chance at cracking the rotation again, assuming all goes well in Double-A Portland first. Rodriguez took the field prior to the club’s afternoon session with the Angels, firing 68 pitches in a simulated game as he prepared for an upcoming rehab assignment in Portland on Thursday.
The 24-year-old southpaw suffered a right knee subluxation during pregame warmups on June 1, and it’s been a slow path to recovery ever since. It’s not the first time Rodriguez has had issues with his right knee — he sustained a similar injury during spring training last year — and this time around, the Red Sox weren’t about to gamble with their starter’s health. Ian Browne of MLB.com reports that Rodriguez was put in a knee brace and underwent exercises designed to help him regain some mobility and stability while he worked back up to full strength on the mound.
He’ll still need to prove he can throw a 75- to 80-pitch outing in Double-A, and barring any significant setbacks, will likely rejoin the Red Sox’ pitching staff when they visit the Rangers next month. In the meantime, the club will continue to cycle starters through the No. 5 spot, which has seen no fewer than three different pitchers since Rodriguez hit the disabled list. The lefty is 4-2 in 10 starts this season after logging a 3.54 ERA, 3.1 BB/9 and career-high 9.6 SO/9 through his first 61 innings.
