A 3-0 victory over Boreham Wood - which saw Ravel Morrison, Ricardo Vaz Te and Kevin Nolan all score - his the Hammers' second in four days as they gear up for the new season
The Premier League club secured a 3-0 win over Boreham Wood at Meadow Park, to follow from their 6-2 success over Cork City on Sunday as Ravel Morrison and Ricardo Vaz Te scored in the first half before Kevin Nolan added a third late on.
And McDonald feels the side are well on course to be prepared for the start of the season, in which they will look to push on from last term’s top-10 finish.
"It was a good workout," he told the club's official website. "Two sets of 45 minutes for the players, which was great and no injuries, which is even better.
"We scored some good goals as well, so we're on track to where we want to be. We've just come back from Cork, we had a good week there, the boys have been getting their fitness up and that certainly showed on Wednesday.
"I thought we were dominant, we passed the ball really well and moved it on with a bit of tempo, more so than we did on Sunday, so that's encouraging. We were nice and tight too, so all in all it's a good start to pre-season and it gives everybody lots of confidence to try and push on."
There were outings for three new signings as Spanish goalkeeper Adrian, Romania international left-back Razvan Rat and former Stockport teenager Danny Whitehead all completed 45 minutes, and McDonald is happy with their progress.
"They've all settled in really well," he continued. "Last week in Cork and now this week back here.
"We switched the teams around again from Cork to try and get a different balance and dynamic between everybody else and everyone's settled in really, really well."
