Weekly Roster Update 5/25/18

Welcome to the R.B.I Baseball May 25th Roster Update! On Fridays throughout the 2018 regular season we’ll put out a roster update for R.B.I 18 that best reflects the state of the game in Major League Baseball. We’ll tune individual players to represent the latest performances. Did Manny Machado mash three taters this week? We’ll be sure to give him a boost in power. Another 10K performance from Chris Sale? We’ll add a bit more movement to that slider. Let’s start off by looking at six week-eight players who really made an impact:

Jacob DeGrom

DeGrom has been DeGrominating the competition all of 2018 and this week was no exception. The Mets righty struck out 13 Diamondbacks and surrendered one lone run over 7 IP. He followed that up by going 7 IP against the Marlins with 8 K and 0 ER. His ERA for the season is now an NL leading to 1.54, and his 11.88 K/9 is both a career high and 4th best in the league. DeGrom has also been limiting HR’s better than ever as he has an impressive 0.35 HR/9 and 6.1 HR/FB ratio. We’ve boosted DeGrom’s Velocity and Curve ratings.

Miles Mikolas

Less than a year ago, Miles Mikolas was pitching for the Yomiuri Giants in Japan’s Central League. This year, he’s throwing complete game shutouts against the Kansas City Royals. The Cardinals righty was absolutely dominant in his last start with 9 strikeouts, 14 whiffs and just one walk. Mikolas has now brought his BB/9 on the year down to 0.90 which is good enough for second best in the majors. A lot of his success is due to his slider which has a 14.4% swinging strike rate and a whopping 7.9 pVAL (a metric that looks to measure the specific value of a pitch; the higher the better). We’ve boosted Mikolas’ Drop, Curve and Speed Difference ratings.

Reynaldo Lopez

After a shaky outing his last time out, Reynaldo Lopez bounced back in style. He went 8 IP with 2 H, 0 ER, 2 BB and 8 K in a fantastic start against the Texas Rangers. While Lopez’ K-rate has yet to resemble the 9.74 he put up in the minors, he’s still striking out more batters than last year. He’s also inducing weak contact at a 25.3% rate which is good enough for 6th best in the Majors. Reynaldo is keeping good company there too as he’s right behind Noah Syndergaard and ahead of Carlos Martinez. We’ve boosted Lopez’ Velocity and Drop ratings.

Matt Kemp

Matt Kemp has been on an absolute tear this past week as he’s slashing .400 / .423 / .600. While the power hasn’t necessarily been there, the XBH have as half of his 10 hits have been doubles. While Kemp’s 22% K-rate on the year is a bit worrisome, he’s still batting .331 on the year with a .186 ISO and a 146 wRC+. We’ve boosted Kemp’s Contact and Fielding rating.

Brandon Crawford

Improved AVG. Improved hard-contact rate. Improved line-drives. Improved HR/FB. You name the stat and Brandon Crawford has improved upon it from 2017. Crawford is currently hitting .309 with a .473 SLG both of which are up nearly .050 points from last year. He’s also currently on pace to hit 20+ homers, something he hasn’t done since 2015. How’s he doing it? By squaring the ball up a lot more – his hard-contact is up 7%. We’ve boosted Crawford’s Contact and Power.

Mark Reynolds

Mark Reynolds has wasted no time in making a positive impact for the Washington Nationals. Since joining the team, Reynolds has played in 7 games, hit 4 home runs, batted .455 and struck out only 12.5% of the time (league average is 22.6%). Small sample size or no, a 1.045 SLG is still incredibly impressive. While the elevated batting average won’t  be sustainable over the course of a full year, his 47.4% hard-contact means that the power is no joke. We’ve boosted Reynolds Power to all fields.
