 Biographical Information
Mike Bolsenbroek has pitched in the minors (3 years), the Netherlands and Germany (where he has won two Pitcher of the Year awards). He threw the first solo perfect game in Dutch national team history.
Bolsenbroek was born in and grew up in the Netherlands. In the 2004 World Junior Championship, he allowed 2 runs (1 earned) in 6 2/3 IP and got the only Dutch win. In 2005, he made his Hoofdklasse debut, going 2-2 with a 2.86 ERA for HCAW, allowing only 14 hits in 22 innings. He was horrible in his lone playoff start, allowing 6 runs and 6 hits in 1 1/3 IP to take a loss. That year, Mike moved to the USA to further his baseball career, first at El Modena High School and then Santa Ana College. He was drafted in the 41st round of the 2006 amateur draft by the Chicago White Sox and in the 26th round of the 2007 amateur draft by the White Sox, but did not sign either time.
Bolsenbroek went to Germany to pitch in 2008, having finished his junior college days. He signed with the Buchbinder Legionäre in the southern division of Bundesliga-1. He was 4-0 with 2 saves and a 1.59 ERA for the club, giving up 26 hits in 56 2/3 IP and striking out 61 while walking 29. He finished third in the division in ERA behind Philipp Hoffschild and Eddie Aucoin. He had the third lowest WHIP after those same two hurlers and his .138 average allowed was the lowest.
Bolsenbroek was 0-1 with a 4.15 ERA in the 2008 European Cup in Regensburg, but with a RA over 9. He took the loss against DOOR Neptunus and was wild (5 walks, 2 wild pitches, 3 runs in 1 IP) in a start against Templiers de Sénart; Hoffschild came in to relieve and rescued the team, which won that outing. Overall, Mike walked 13 in 8 2/3 IP in the Cup.
Mike did not join the Legionäre for the Bundesliga playoffs as he was drafted in the 42nd round of the 2008 amateur draft by the Philadelphia Phillies. This time, he signed, a 7-year deal. He was the second Dutch player in Phillies organizational history, following Mike Crouwel (1992). Despite standing 6' 8", he was only the 4th-tallest Dutch hurler in Organized Baseball in 2008, following Loek van Mil, Rick van den Hurk and Swen Huijer.
Bolsenbroek pitched 5 games for the 2008 GCL Phillies, going 0-1. He allowed 3 runs (1 earned), 8 hits and 5 walks in 6 1/3 IP while fanning 5. In 2009, he was 2-2 with a 2.03 ERA and 30 K in 31 IP for the GCL Phillies. He moved up to the Williamsport Crosscutters in September and allowed one run in 4 2/3 IP. He went 0-1 with a 3.38 ERA in 18 games for the 2010 Lakewood BlueClaws. He finished his US career 2-4 with four saves and a 2.55 ERA in 41 games (two starts). In 74 IP, he allowed 65 hits and 38 walks while striking out 64.
Mike returned to Regensburg in 2011 and was 6-0 with a 1.57 ERA, striking out 79 in 57 1/3 IP. He led the southern Bundesliga-1 in ERA, tied René Franke for second in wins (behind former major leaguer Dusty Bergman), was third in strikeouts and was third in WHIP. He helped the club win another Bundesliga title. He was named the southern Bundesliga-1 Pitcher of the Year.
In 2012, Bolsenbroek was 7-0 with a 1.96 ERA and 71 K in 59 2/3 IP. He finished 4th in ERA (between Patrick Haugen and Justin Kuehn), was 6th in strikeouts, tied Haugen and Kuehn for the win lead, tied for second with two saves and led with a 0.87 WHIP (.10 ahead of Kuehn). He lost Pitcher of the Year honors to Nick Renault. He was 1-1 with a 2.13 ERA in the 2012 European Cup, fanning 13 in 12 2/3 IP, beating Technika Brno and losing to Rouen Huskies. He tied Chris Mezger and Dushan Ruzic for second in Ks, one behind Jorge Balboa. During the 2013 World Baseball Classic Qualifiers, he pitched for Germany. He tossed 5 1/3 innings (5 H, 2 BB, 6 K, 1 UER) in a win over the Czech national team and Michal Sobotka; the lone run came on an error by Donald Lutz on a pick-off attempt in the 5th, when Germany was up 3-1 en route to a 16-1 romp. Martin Dewald relieved him in the 6th.
Bolsenbroek was 9-1 with a 0.81 WHIP, 86 K and a 1.46 ERA in 2013. He won his second Pitcher of the Year award, beating out Luke Sommer. In the 2013 European Cup, he lost to both the Amsterdam Pirates and Eagles Prague, with a 5.40 ERA.
In the 2014 European Cup, he had a no-decision in a Regensburg loss to Draci Brno but beat the Templiers de Sénart. He fanned 16 in 13 2/3 IP and had a 1.32 ERA. He tied Wilson Lee for the most strikeouts. In the 2014 Bundesliga, he was had a 6-1, 2.24 record with 75 K to 13 BB in 60 1/3 IP. He was third in ERA behind Sommer and Jan-Niclas Stöcklin, tied Kyle Waddell for 4th in strikeouts and tied for 5th in wins. He pitched for the Netherlands in the 2014 European Championship. On September 14, he threw a 7-inning mercy rule perfect game against the Greek national team in a 11-0 win. It was the second perfecto in the history of the Dutch national team, 50 years after Rob Hoffmann and Herman Beidschat had combined on one in the 1964 European Championship; interestingly, Mike's 3B (Nick Urbanus) was the grandson of the 2B in the 1964 game (Han Urbanus). Bolsenbroek fanned 10 and needed just 73 pitches. Coincidentally, there had been another no-hitter earlier in the day as Belgium's Thomas De Wolf had thrown one. In his other outing, Mike tossed a three-hitter to shut out the defending champion Italian national team in their first loss of the 2014 Euros; three Dutch pitchers combined to top Italy the next day to give the Netherlands the title. Bolsenbroek won Best Pitcher honors for the 2014 Euros. Curt Smith beat him out for European Championship MVP.
