They should just basically bullpen 2-3 games a week after Kyle and Yu with the expanded rosters at 30. Yeah, I would give Lester a soft cap of twice through the order (basically he can earn another inning if he's pitching well), Chatwood a pretty hard cap of twice through the order, and Mills probably limit to once through. We've got several guys in the pen who can go multiple innings, so we should feel comfortable piggybacking with contrasting styles: for example something like Lester-Underwood, Chatwood-Wieck, and Mills-Alzolay. I think there are several ways that this weird season hurts the Cubs worse than the average team, but this is a way it helps. The Cubs came into the spring with like 14 credible guys fighting for 8 bullpen spots, this gives them an extra couple of weeks to evaluate in real games which of those guys should stick. Obviously the cost of failure is much higher in a shortened season, but given the circumstances every team is going to be asking for a lot more innings out of their pen, and probably only the Rays and Padres have a better like 11th arm out there.
