After his May 1 start in Double-A, McDonald had a 5.27 ERA and .271 opponents' batting average. In his remaining 17 Double-A starts, the right-hander posted a 2.56 ERA with a .213 opponents' batting average in 91 1/3 innings.
Scouting report: Fastball is an average 88-92 mph as a starter but was up to 96 as a reliever. Changeup, around 75 mph, is a plus pitch he'll throw at any time. His breaking ball, a curve, is above-average and a plus offering at times. He'll add and subtract from his pitches to keep hitters off-balance. Has solid-average command of all pitches and his makeup is off the charts.
Upside potential: Still just scratching the surface, McDonald could fit in well to the back end of a bullpen, especially with the increased velocity he showed. As a starter, he could be a No. 4 type of guy right now.
He said it: "It wasn't nervousness, it was an excitement. This is where I wanted to be. This is where I expected to be." -- On his Major League postseason debut
They said it: "He'd started for us his entire career, then switched to the bullpen. The thing that stood out for me was the four more feet of fastball. He was up to 96 mph. It provides some versatility for us. We can leave him in the bullpen or we can give him a chance for a rotation spot." -- Dodgers Farm Director De Jon Watson
