Good to see Donald making a second century in consecutive matches. Forget that it's only second XI cricket, the important thing is that he's spending time in the middle and feeling good.
The second XI don't play next week. So if they did want to give him a third match in the seconds, that would mean the earliest he would be available to play in the Championship would be away to Somerset (match number 6). But if they're happy that just these two matches are sufficient, then he could play vs Lancs next week (match number 4).
Right now, it's probably Organ's place which is most up for grabs. He hasn't really featured in either match so far - and even though the same applies to Dawson, he is clearly going to be ahead of Organ in the pecking order. It therefore makes this week's match vs Kent very important for Organ. We don't need seven bowling options, so he needs to be contributing with the bat to justify his place.
