HR/FB Rate Validations Using xHR/FB Rate – The Leaders

For the third week in a row, we once again use Statcast’s Brls/BBE (barrels per batted ball event) as the primary component of my xHR/FB rate, to analyze hitter HR/FB rates. Today, I’ll use xHR/FB rate to validate some of the surprise HR/FB rate leaders. This doesn’t necessarily mean the hitter is going to sustain this pace — their Brls/BBE could certainly decline, and given that it’s likely quite high now, it probably will — but that what has happened so far looks like a legitimate power breakout, rather than a small sample fluke.

Prospect Performers: The NL East

At the beginning of the 2017 season, I wrote pieces reviewing the potential impact rookie hitters in each league for 2017. Today, we continue a semi-regular review of how those players are actually performing. The American League East was the first up for review and we hit the NL East today.

1. Dansby Swanson, SS, Braves: Swanson entered the year as one of the favorites for NL Rookie of the Year after performing well in a brief MLB showing in ’16. The 23-year-old infielder has seen his BABIP drop from .383 to .242, though, and that’s dragged down his triple-slash line to just .190/.261/.270.  He’s hitting .255 in May – up from .156 in April – but the swing-and-miss rate is actually up and nearing 30% this month. The team wasn’t expected to win in 2017 so the club can be patient with Swanson but he has a lot of work to do before he’ll consistently produce at even a league-average rate.

2. Koda Glover, RHP, Nationals: Glover was expected to be a key high-leverage reliever for the Nationals in 2017 but an injury knocked him out for close to three weeks. When healthy, he’s shown excellent control with just two walks in 11.2 innings. However, he’s struck out just nine batters and his swinging strike rate is just 8.4% (In comparison, Craig Kimbrel leads relievers at 23.7% and Chris Devenski is second at 21.1%). Glover has some work to do before he’s considered an elite relief option — but the potential is still there.

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.

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.
