Traditional Big XII baseball power Oklahoma State has proven to be just a little too much to handle for the 21st-ranked University of New Mexico Lobos so far.

As in the first game of the three-game nonconference series, UNM held a lead Saturday before the Cowboys stormed back — thanks to first baseman Tanner Krietemeier — and stole another win, this time by 15-14 in 13 innings.

The Lobos held a 14-12 lead with two outs in the top of the ninth inning, but with runners on first and second base, Krietemeier roped a two-run single to right field off UNM pitcher Will Mathis to send the game to extra innings.

After three scoreless innings, Cowboys center fielder Jarrett Higgins doubled up the middle to drive in the tie-breaking run.

Third baseman D.J. Peterson again led Lobo hitters, going 3-for-4. His grand slam in the second inning rallied UNM back from an early 5-0 deficit. Peterson finished with five RBIs and drew two walks.

UNM (0-2) will try to get its first win of the season in its final game against Oklahoma State (2-0) at 1 p.m Sunday.

Game 2: Eastern New Mexico 6, New Mexico Highlands 5

The Greyhounds swept the afternoon doubleheader at Brandt Park because of what head coach Steve Jones called “early-in-the-year mistakes.”

A Derek Crenshaw three-run homer to left opened up an early 3-0 lead in the first inning of Game 1 for the Greyhounds. Baserunning mistakes plagued the Cowboys despite eight hits. NMHU center fielder Jordan Goliat was the only Cowboy with multiple hits.

In Game 2, Highlands had three errors that led to four Greyhound runs. Senior catcher Chris Pile went 2-for-3 with two doubles and three RBIs.

The Cowboys (1-2) will go for a split of their four-game home series against the Greyhounds (6-1) at noon Sunday.
