David Grewe Season 2025
David Grewe enters his third season as LSU’s associate head coach after helping lead the Tigers to the 2009 national championship.
Grewe, the head coach at Michigan State from 2006-08, was named the Tigers’ associate head coach on June 26, 2008. He serves as LSU’s pitching coach and recruiting coordinator.
Grewe’s hiring reunited him with Paul Mainieri, as he worked under Mainieri at Notre Dame from 2003-05. Grewe was also reunited with LSU hitting coach Javi Sanchez, who played catcher at Notre Dame under Grewe’s supervision in 2003 and 2004.
Grewe has provided national recognition for LSU in the recruiting realm, as his 2010 class was rated No. 1 in the nation by Collegiate Baseball magazine. Eight players in LSU’s 2010 class were drafted, another was the NJCAA Division II Player of The Year and two others were named their respective high school state Players of the Year.
Grewe’s 2009 recruiting class – his first at LSU — was rated No. 3 in the country by Collegiate Baseball. Five members of that class were selected in the MLB Draft, and four of the players earned All-America recognition during their careers.
Grewe made an immediate impact upon the LSU program in 2009, directing a Tiger pitching staff that finished No. 6 in the nation in strikeouts per nine innings (9.5), No. 7 in walks allowed per nine innings (2.6) and No. 9 in earned run average (4.01). LSU posted the best ERA in the Southeastern Conference for the first time since 2002.
“David Grewe has made a tremendous impact on our program in a very short time,” Mainieri said. “His work as our pitching coach was vital to our drive to the national championship, and he is recognized as one of the best recruiters in the nation. It’s very apparent David is proving every day that he is one of the outstanding young coaches in college baseball.”
Grewe tutored three All-America pitchers in 2009 – right-handers Louis Coleman, Matty Ott and Anthony Ranaudo.Coleman was the ’09 SEC Pitcher of the Year, recording a 14-2 record, a 2.93 ERA and 142 strikeouts in 129 innings. Coleman finished the season ranked No. 2 in the nation in wins and No. 4 in strikeouts.
Ott, the SEC Co-Freshman of the Year, established an LSU single-season record with 16 saves. A finalist for the NCBWA Stopper of the Year award, Ott posted a 4-2 mark and a 2.68 ERA with six walks and 69 strikeouts in 50.1 innings.
Ranaudo, an all-SEC selection and a member of the College World Series all-tournament team, was 12-3 on the year with a 3.04 ERA and 159 strikeouts in 124.1 innings. Ranaudo was No. 3 in the nation in strikeouts, and he became the first LSU pitcher to lead the SEC in Ks since Kurt Ainsworth in 1999.
Under Grewe’s direction, Ranaudo in 2010 continued to develop as one of the nation’s top pitchers, and he was selected in the compensatory round (39th pick overall) of the MLB Draft by the Boston Red Sox.
Grewe also instructed LSU right-hander Austin Ross, who was chosen in the eighth round of the 2010 MLB Draft by the Milwaukee Brewers.
During Grewe’s three-year tenure at Michigan State, the Spartans compiled a 75-85 record, including a 42-53 mark in Big Ten play. The Spartan baseball program was in contention for postseason play on the final day of each of Grewe’s three seasons, and the program compiled the Big Ten’s top recruiting class for the 2009 season, according to Baseball America.
In 2008, MSU recorded victories over traditional powers Stetson and Western Carolina while also winning a game against College World Series participant Rice. In 2007, the Spartans defeated South Florida, Oklahoma and won three of four at Ohio State.
During Grewe’s three seasons, seven MSU players were selected in the MLB draft. Three players were taken in the 2008 draft, topping each of the previous two years when two players were selected. The Spartans also enjoyed notable achievements in the classroom under Grewe. Thirty MSU baseball players were named Academic All-Big Ten during his tenure, including 12 student-athletes in 2006.
Grewe arrived in East Lansing following three years at Notre Dame (2003-05) where he served as the recruiting coordinator and the hitting and catching instructor under Mainieri. During his tenure, the Irish compiled a combined record of 134-54-1 (.712), including three straight Big East Tournament championships and three-consecutive NCAA Regional appearances.
Over his three-year period with Notre Dame, Grewe helped the squad to the fourth-most wins in all of NCAA Division I.
At Notre Dame, Grewe established himself as one of the nation’s top recruiters. He helped attract two top-10 recruiting classes to South Bend, Ind., including the 2004 Class (ranked No. 6 by Baseball America) and the 2006 Class (ranked No. 7 by Team One Baseball).
While on the Notre Dame coaching staff, Grewe also supervised the transformation of Sanchez, from starting shortstop (2002) to all-star catcher. With no catching experience prior to 2003, Sanchez emerged as a polished catcher and clutch hitter, earning 2003 Big East Tournament MVP honors and a spot on the NCAA Fullerton Regional All-Tournament team. His steady development and refined defensive skills prompted the Minnesota Twins to select Sanchez in the 14th round of the 2004 Major League Baseball Draft.
Grewe coached 13 players at Notre Dame that were drafted or played professional baseball. He also recruited five players that were drafted out of high school and continued their playing career at Notre Dame.
Grewe spent two years as an assistant coach at Central Michigan (2001-02), where he coached the infielders and catchers and served as hitting instructor under Judd Folske. He was also extremely involved with the pitchers and called pitches for CMU pitchers during the games. Grewe coached five CMU players who went on to professional baseball.
In 2001, the Chippewas set single-season records for runs scored (470) and RBI (422). The 626 hits (second), 988 total bases (second) and 69 home runs (third) all ranked among the top single-season totals in CMU history.
Grewe spent two seasons as an assistant coach at the University of Chicago (1999-2000) under Brian Baldea, serving as hitting instructor, infield coach and recruiting coordinator. In 2000, the Maroons ranked No. 19 in NCAA Division III in batting average (.347) while averaging 8.47 runs per game.
Grewe earned three letters at Dayton (1996-98) while starting games at catcher, first base and third base. He started at third base for the 1996 team that set the Dayton record for wins, including an upset victory in Alex Box Stadium over eventual national champion LSU.
The Royal Oak, Mich., native graduated from Dayton in 1998 as a sports management major, with a double minor in marketing and public relations. While coaching at Central Michigan, he served as a graduate teaching assistant while studying towards a master’s degree in athletic administration.
Grewe married the former Annie Brammer, a native of South Bend, Ind., in the fall of 2006. The Grewes have three children – Charlie (3), Mary Claire (2) and Jack, born in September 2010.
