Bullpen Report: May 21, 2017

There wasn’t too much noteworthy bullpen activity on Saturday, besides Addison Reed‘s high-wire act against the Angels, which he and the Mets ultimately survived. Sunday was much the same, save for a few relevant items:

  • Koda Glover was the first man out of the Nationals bullpen, and it came with the Nats leading 3-2 with two outs and the tying run on second base in the eighth inning. Despite the fact that lefty Nick Markakis was due up, and left-hander Oliver Perez was getting loose along with Glover, manager Dusty Baker went with the righty and the decision paid off. Glover fanned Markakis on a 96 mph fastball, then, with the same score in the bottom of the ninth, Glover came back out to the mound. He surrendered a leadoff single, but then induced a double-play lineout and a game-ending popup. It was the 24-year-old’s third save of the season, and it came just two days after Shawn Kelley, who was seemingly first in line for saves in a beleaguered Nationals bullpen, pitched in the seventh inning of a tie game. As such, the bullpen situation in Washington remains highly volatile and red. Glover slots into the closer’s spot on the chart for now, but that is subject to change at any moment. Expect future save opportunities to go to one of the two, at least, though neither is a clear long-term favorite.

There are three guarantees in life: death, taxes, and Cody Bellinger home runs. In 100 plate appearances, Bellinger has nine bombs and he’s leading the National League rookies in multiple offensive categories. He is also sitting on a 26.7% home run/fly ball ratio.

Roto Riteup May 20, 2017

Joey Gallo keeps hitting the ball, and he’s hitting the ball hard. His .188 batting average this season is kind of joke sitting next to his .500 slugging average, but he does have 13 home runs in 42 games and he’s showing more discipline at the plate. But you really can’t get worse than a 63.3% strikeout rate he left behind him last season.

Bullpen Report: May 19, 2017

Another exciting night of bullpen activity with full slate of games on Friday…

  • Mariners general manager Jerry Dipoto indicated in an interview on Fantasy Sports Radio that 26-year-old James Pazos could be first in line for save opportunities while Edwin Diaz works through mechanical issues that led to his demotion from the closer’s role earlier this week. Pazos has intriguing numbers across the board in 18.2 innings this year: he boasts a strong 30.9% strikeout rate, a 60.9% ground ball rate, and a tidy 2.41 ERA/2.66 FIP/2.78 xFIP. Diaz was so dominant last season that it remains likely he will eventually harness his mechanics and find his way back into the Seattle bullpen’s most prominent role. He pitched two scoreless innings on Friday, in which he allowed two hits and notched two strikeouts in the eighth and ninth innings of a tie game at home. Despite the scoreless outing, Pazos is worth a speculative add in most formats in case he gets an opportunity to close and runs with it. His numbers seem to indicate that he’s capable of doing so.
  • Seung Hwan Oh blew a one-run save opportunity against the Giants on Friday. He allowed two singles and a go-ahead two-run double. Oh is now 10 for 12 in save opportunities, a nice recovery in that department after a very shaky start to the season. However, Oh’s peripherals point to a problem: his 16.3% strikeout rate this year is roughly half of the 32.9% K% he put up last season. He’s also allowed three home runs and nine walks in 21.1 innings. Add it all up, and Oh has an unsightly 4.91 FIP and 5.70 xFIP. Meanwhile, former closer Trevor Rosenthal has been mostly terrific in a set-up role (although he was charged with a blown save in Wednesday’s extra-inning loss to the Red Sox). Rosenthal has a 44.3% strikeout rate in 15.1 innings, and he should represent a threat to the struggling Oh. If Oh can’t turn it around soon, the Cardinals may have to make a move. The situation has been updated to yellow.

Minors To Majors: Hitter Grades & Minor League Results

I’ve made it almost a month since I made the following declaration on investigating prospect Hit grades:

I am going to stay away from more Hit tool predictions until I have collected every one of MLB.com’s prospect grades from 2013 and 2014, not just the top 100. I probably will not be able to compare many to their major league stats but I can with Triple-A.

I broke my position after collecting MLB.com’s 2013 grades. I ventured forward without the 2014 grades. With this larger and more diverse dataset, I compared the hitters’ grades to their batting average, home runs, and stolen bases in both AA and AAA.

Trying to better understand the Hit tool stems from finding it doesn’t contain any predictive power. When looking at players with different grades, major leaguers ended up posting similar batting averages. I concluded two issues were causing the production to level out.

First, hitters needed a talent and/or production baseline to get into the majors. Some hitters with below average grades were under-graded and produced up to the MLB baseline. Additionally, “better” hitters were over-graded but still had just enough talent to make the majors. This talent convergence tends to average out the grades.
