Bowa had been a candidate for the Marlins' managerial vacancy, but that job could be headed to Don Mattingly.
The team announced last week that Rick Kranitz and John McLaren will be the bullpen coach and catching coach, respectively. Hitting coach Steve Henderson and pitching coach Bob McClure previously agreed to contracts for next season. The Phillies will not have an assistant hitting coach, like they had the previous three seasons.
They still need a first-base coach, who could be hired after this week's organizational meetings in Clearwater, Fla.
