Jim Riggleman and the interim title: Take 2

Leave a comment

For the second straight year Jim Riggleman took over a horrible team at midseason as interim manager. For the second straight year he helped the team become slightly less horrible. And for the second straight year he probably won’t be asked back.
Here’s what Nationals general manager Mike Rizzo–himself an “interim” GM until just recently–said about Riggleman’s chances of managing the team in 2010:

I think Riggleman really did a good job handling the ball club after the All-Star break. I think he put us on pace to really focus and bare down on the fundamentals of the game, to play cleaner and more efficient ballgames. He had the players playing at a high level. I think he has done the best job he could with the ability level that he has.



This is the evaluating time of the year. We are all being evaluated, Jim included. Jim has done a great job. It’s going to be an intense offseason and a busy one. The ultimate goal is to make us a better ball club.

Riggleman has gone 29-42 since taking over the Nationals from Manny Acta and was 36-54 after taking over the Mariners from John McLaren last season. Obviously his combined 65-96 (.403) record in those two stints is hardly impressive, but consider that Washington and Seattle were a combined 51-108 (.320) before he came along. Over the course of a full season, that amounts to a 13-game improvement.
On the other hand Riggleman has now managed 1,245 major-league games for four different teams and has a lifetime 551-694 (.443) record, so while he may be good at turning historic awfulness into run-of-the-mill awfulness he hasn’t done much more than that with past chances. Riggleman is certainly a legitimate candidate for the full-time job, but my guess is that he’ll be part of the interview process before eventually giving way to a bigger, more fan-pleasing name.

Aledmys Diaz is trying to improve his defense with strobe glasses

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.

Eduardo Rodriguez could rejoin the Red Sox rotation in July

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.
