Johnny Football will become Johnny Baseball on Sunday at Rangers Ballpark.Johnny Manziel, the Texas A&M quarterback and reigning Heisman Trophy winner, will throw out the ceremonial first pitch prior to the Rangers-Angels game.Manziel has a baseball background, too, as he grew up wanting to be a big-league shortstop. But his baseball days are in the past, and he is now more known for touchdown passes than runs.The Aggies went 11-2 and won the Cotton Bowl last season behind Manziel, who became the first freshman to win the prestigious Heisman.Manziel is one of several highlights the Rangers have in store for their opening weekend. Here are the others:• To cap off an all-A&M day with Manziel on Sunday, the Texas A&M University Singing Cadets will perform the national anthem and God Bless America.• Rangers’ Opening Day, as previously announced, will have Robbie Parker throw out the first pitch. Parker, a longtime Rangers fan originally from North Texas, is the father of 6-year-old Emilie Parker, who was killed in the Sandy Hook Elementary School shooting in Newtown, Conn., last December.• Texas country recording artist Jack Ingram will perform the national anthem on Rangers’ Opening Day, and Tech. Sgt. Shonda Winkler of the 531st Air Force Band will sing God Bless America in the seventh inning.• Saturday’s pregame events include honoring two award winners from last season, Adrian Beltre (2012 Gold Glove and Platinum Glove) and A.J. Pierzynski (2012 Silver Slugger). Christian music artists FourTwelve will perform the national anthem and God Bless America, and there will be a concert beginning at 1:30 p.m. on the North Lawn featuring country singer Mark McKinney.• Ticket situation as of Monday afternoon: Rangers’ Opening Day is sold out; there were approximately 3,000 tickets left for Saturday; and there were 12,000 available for Sunday.
