The Michigan staff continues to fill out its 2015 class in advance of the early signing period in November, today gaining two more commitments, both right-handed pitchers.
Miller is a 6-3, 205-pound righty out of Soquel H.S. in Soquel, California, located near Santa Cruz. Miller was voted Pitcher of the Year for the Santa Cruz Coast Athletic League, after going 6-1 in 11 regular-season appearances with 44 strikeouts and a 2.53 ERA in 51 1/3 innings. He has a four-pitch arsenal: a two- and four-seam fastball, circle change, and curveball. His velocity has increased this summer, with his fastball clocked at 91 mph recently.
Miller was recently selected to compete for the Oakland A's team at the "prestigious and heavily scouted" Area Code Games to be held August 4–9 in Long Beach.
"Being with the top 240 players in the country — it's a real honor," Miller said Wednesday. "I'm excited for where my baseball career, with the help of my coaching, is taking me right now."
That article (from July 23) indicates that Miller had earlier committed to Saint Mary's College but decomitted at the beginning of this summer. It also mentions plans of official visits to Michigan and Baylor and an unofficial visit to UC Santa Barbara, but he changed those plans today with his verbal commitment to Michigan.
I don't have rankings info on Miller—Prep Baseball Report doesn't cover California, and the Perfect Game rankings are paywalled. His credentials above seem quite good, however. It's also encouraging to see the Michigan staff continue to be able to attract players from California, having already brought in Ramsey Romano and Jackson Glines, with juco transfer Cody Bruder joining the team this year.
I haven't been able to dig up much on Karcher, but here's what I've found: Perfect Game has him as a 6-4, 175-pound righty, with a best-recorded fastball of 88 mph. For at least the last two years, he has attended and played baseball at Ponte Vedra H.S. in Ponte Vedra, Florida, located near Jacksonville, helping his team win a state championship in 2013. But he's apparently moving to Saline for his senior year of high school, attending Saline High. It's possible he's originally from Saline, and his family is now returning there.
Again, any rankings are n/a. PBR recently expanded to Florida, but they don't yet have rankings for that state.
