I’ve been thinking about the value of coaches lately, in part because the Cardinals only had to shell out $750,000 per season to make Dave Duncan the highest-paid pitching coach in baseball and in part because the Phillies let first base coach Davey Lopes go over failed contract talks that probably involved a difference of $100,000 or less.
If someone like Duncan who’s considered one of the best pitching coaches in baseball history is only worth $750,000 per season and someone like Lopes who’s been praised constantly for his huge impact on the Phillies’ historically great stolen base numbers leaves over an extra $100,000 … well, do teams really value coaches very much?
After all, the average utility infielder makes more per season than both Duncan and Lopes combined.
It’s a tough question to answer, largely because it’s tough to evaluate coaches in anything resembling the way we evaluate players. There are enough statistics and metrics and tools for me to opine with a decent level of confidence that, say, Albert Pujols is usually worth about 85 runs per season above a replacement-level first baseman. But how much is Lopez worth above a replacement-level first base coach?
I have no idea, but Bill Baer of Crashburn Alley crunched some numbers in an effort to find out and what he found is pretty interesting. I won’t spoil the conclusion because you really should read the whole article, but I will say that like me he agrees the Phillies letting Lopes go over $100,000 would be a mistake. And unlike me he has actual data to support that opinion. Check out Baer’s analysis and also read the comments section for an interesting look at the value of top-notch coaches.
In a wave of prospect advancement news on Sunday, the Rockies have joined the fray. The Astros are calling up Alex Bregman. The Diamondbacks are calling up Braden Shipley. And the Rockies will call up outfield prospect David Dahl on Monday, Nick Groke of The Denver Post reports. The Rockies are expected to designate outfielder Brandon Barnes for assignment to create roster space.
Dahl, 22, was selected by the Rockies in the first round — 10th overall — in the 2012 draft. He started the season at Double-A, batting .278/.367/.500 with 13 home runs, 45 RBI, 53 runs scored, and 16 stolen bases in 322 plate appearances. He earned a promotion to Triple-A Albuquerque earlier this month. In 16 games there, Dahl has hit an outstanding .484/.529/.887 with five homers, 16 RBI, and 17 runs scored in 68 plate appearances.
Dahl is considered the Rockies’ second-best prospect and #40 overall in baseball according to MLB Pipeline. He got some camera time during the 2016 Futures Game two weeks ago, going 0-for-2.
David Robertson got the win in both White Sox victories today, a double-header versus the Tigers. In the first game, he got the final out of the eighth inning and pitched a scoreless ninth before the White Sox walked off on an Adam Eaton RBI single.
It was the second game that made things interesting. Robertson took the mound at the start of the ninth inning staked to a 4-1 lead. He’d fork up a leadoff home run to Nick Castellanos. Then, after getting two outs, served up another solo shot to Tyler Collins followed by a game-tying Jarrod Saltalamacchia dinger. Robertson would get out of the inning without any further damage.
In the bottom of the ninth, Melky Cabrera sent the White Sox home winners again, drilling a walk-off RBI single. That gave Robertson the win, his second of the afternoon. As Baseball Tonight notes on Twitter, Robertson is the first player in the last 100 years to give up three home runs in an inning or fewer and still wind up with the victory.
Robertson has had a rough go of it since the All-Star break. He yielded four runs in his first appearance back on July 18. On the season, he’s saved 23 games in 27 appearances with a 4.46 ERA and a 50/21 K/BB ratio in 40 2/3 innings.
